A Christian woman has been beaten to death in Uganda by a mob of Muslims because she and her family had not heeded their warning to stop preaching the gospel. Her brother-in-law was killed last month for the same reason.

Mamwikomba Mwanika, a mother of eight children, was taken from her home in Kalampete village in Kibuku District and killed last week, according to Morning Star News. 

She opened the door of her home to a mob of Muslims who demanded to see her husband, also a Christian, saying: "Your husband has followed the religion of his brother, and we had warned you people to stop these activities, but our message has landed on deaf ears."

Mwanika's husband, George Mwanika, was not at home which angered the mob. His brother, Samson Nfunyeku, was killed in the same village last month for debating with Islamic scholars.

Mwanika's 13-year-old daughter told Morning Star News that the mob then "dragged our mother outside the house as she screamed and cried for help."

She was later found in a pool of blood about 100 metres from her home by her husband and neighbours. She was still alive when they found her, but died en route to hospital.

"I know that the attackers are looking for me," George Mwanika said following the incident. "We are seeking God's protection and His peace. May God give me the courage to continue sharing the love of Christ to those who are lost, as Jesus said we should love our enemies."

Uganda is a majority-Christian nation, however some eastern regions are dominated by Muslims.

Attacks and killings of converts are not uncommon in the region; a Christian woman was gang raped and another poisoned and killed in eastern Uganda earlier this year.

Ugandan authorities have warned of a growing threat of Islamist extremism within the country in reaction to Uganda's military involvement in Somalia as part of an African Union force fighting al-Shabab terrorists.
